Referring more particularly to the drawings,

I0 designates a table top supported by legs II.

A paste container generally designated by the numeral I2 is supported by the table in any approved manner. This container extends length- 30 wise of the tableand has a chamber i3 enclosed by an end wall I4 and side walls I5. The chamber I3 is located substantially centrally of the tank or container I2 and `has its side walls I5 sheared off, as shown at I6, so that one end of 35 the chamber opens intodthe tank I2. The bottom of the chamber I3 is curved upwardly, as shown at I'I, and joins the end wall i4. The curved portion I'I is concentric with the outer surface of a pasting cylinder I8.

The pasting cylinder is driven by'an `axially mounted shaft I9 which carries the cylinder and, in turn, is mounted in bearings 2l) formed integrally with side plates 2| of the table IIJ. The shaft I9 is driven in any approved manner. 45

When the pasting cylinder i8 is revolved the portion which is suspended in the chamber `I3 picks up` the paste on its surface and carriesl it upwardly through the opening 22 in the table I0. A scraper, however, is employed for main- 50 taining a predetermined thickness` of the vpaste on the cylinder `and removes excess paste therefrom. This scraper is in the form of a curved plate 25 having an edge 26 extending the length of the cylinder I8. This plate is provided with a v pair of side arms 21 which engage the ends of the cylinder for removing paste. The plate is supported by means of ears 28 and a rod 29 extending between the side walls of the table and 5 supported thereby.

The edge 26 of the scraper per se may be adjusted towards or away from the surface of the cylinder I8 by means of a rod 39 which extends to one end of the table and is provided with a 10 manipulating rod (not shown). This rod is pivotally connected at 3| with ears 32 connected tothe plate 25.

A frame, generally designated by the numeral 35, (Fig. 1) has one end pivotally mounted on a l5 shaft 36 and the ends of the shaft are mounted in a split bearing formed of the members 31 and 38. while the member 38 is pivotally connected at 39 with the member 31 and is swingable outwardly from the member 31 when it is desired to remove the frame 35. The section 38 of the bearing is held in place by means of a yoke 40 pivotally mounted at 4| on the member 31. A screw 42 projects upwards from the upper end of the yoke 48 and carries a manipulating member or nut 43 which when revolved in the` proper direction clamps down against the member 38 for holding it in position upon the bottom bearing member 31. It will be noted from Fig. 3 that sub- BQE; stantially identical constructions of the bearing members and locking yokes are provided at each side of the machine.

The frame is pivotally mounted upon the shaft 36 and is swingable. on its Kpivot so that 35 the free end 45 may be moved outwardly from the pasting cylinder I8 when itis desired to repair or clean any of the parts carried by the frame. The opposite or free end 45 of the frame is supported by .means of, lugs 46 which extend outwardly from the end of the frame and these 'lugs -receive set screws 4`| which support the weight of the frame uponthe table land also for the purpose of properly adjusting the height of the free end of the frame relative to the table I0. The height of the .free end 45 of the frame *from the table depends upon the wear on the parts of the device and also the thickness o-f the soles passing through the device as will be presently explained.

The frame consists of a pair of side members generally designated by the numerals 48 and 49 (Fig. 2). Each side member consists of a pair of sections 5I] and 5| which are secured together and maintained in spaced parallel relation in a Amanner which will be presently explained.

A driven roller 52 has reduced portions 53 at its opposite ends which are received within bearings 54 of the side members 48 and 49.

Between lthe sections 50 and 5| of the side member `48 and completely housed by said sec-` tions is a sprocket 55 which is secured to the reduced portion 53 of the roller 52 in any approved manner. A chain 56, as shown in Fig.

4, is trained on the sprocket 55 and also on a sprocket 51 secured to the shaft 36 whereby the chain vis driven positively by the rotation of the shaft 36.

A third sprocket 58 is secured to a shaft 59 which is mounted .in bearingsk 60 carried by the side members 48 and 49 of the frame.

"` The shaft 36 is provided with a plurality of spaced -.discs 6| and thesediscs are maintained in spaced relation by sleeves 62 received by the shaft 36. These discs are relatively thin so that .they will engageas little of the upper surface of The member 31 is secured to the table lilV the soles as possible. The shaft 59 is also provided With a plurality of spaced discs 63 which are held in spaced relation by means of sleeves 64 received by the shaft 59. These discs are likewise relatively thin sol that they will engage as little of the surface of the soles as possible.

A spacer rod 65 isl provided at its ends with reduced portions 66 (Fig. 3) which are threaded to receive nuts 61 and shoulders which abut the inner faces of the members 48 and 49 for aiding in securing the members 48 and 49 in spaced relation.

Rods 10 and 1| also act to maintain the members 48 and 49 in spaced relation and are also provided with reduced portions 12, the reduced portions at their ends to be received within passages 13 of the members 48 and 49. rIhe reduced portions provide shoulders 14 which abut the inner faces of the members 48 and 49 while nuts 15 threaded onto the ends of the rods not only l secure the rods in place but also secure the members 48 and 49 in spaced relation.

A plurality of relatively thin plates 16 are provided with passages 11 to receive the rods 10 and 1| and these plates are secured to the rods in any approved manner. The lower edges of these plates are curved, as shown at 18 to engage the upper faces of the soles when said soles are passing between the plates 16 and the exposed surface of the pasting cylinder I8 and for curving l the soles slightly over the curved exposed portion of the cylinder.

Co-operating with the discs 63 on the shaft 59 are a plurality of plates which have their upper edges 8| disposed substantially in a horizontal plane and these plates are provided with openings 82 to receive a rod 83 which is secured to the side walls of the table.

The inner free ends of the plates, as shown at 84 (Fig. l), are curved to conform to the curvature of the pasting cylinder I8 and normally rest thereon. These plates are relatively thin and have substantially the same thickness as the discs 6| and 63. The plates are secured to the shaft 83 in any approved manner.

One end of the shaft or rod 83 (Fig. 2) is supported by a pintle 85 which is carried by a boss 86 secured to a side wall 2| of the table or formed integrally therewith. The .pointed end of the pintle, as shown at 81, is received within the socket of the rod 83.

A movable pintle 81a is provided with a pointed end received withina complementarily formed socket 88 in the other end of the rod or shaft 83. The pintle 8la is provided with a reduced portion 89 slidably mounted in a bearing 90 formed in a boss 9| which is also formed integrally with a side wall 2| of the table. The boss is provided with a pocket 92 to receive a spring 93 which has one end in engagement with a shoulder 94 on the pintle 81 while the other end of the spring engages the bottom of the pocket 92. The outer end of the rod or reduced portion 89 of the pintle is provided with a nut or collar 95 received in a pocket 96` of the side wall 2| for maintaining the pintle in position while permitting the spring 93 to force the pintle into the socket 88 in the rod 83. By this means the rod 83 together with its connected blades or plates 88 may be readily removed from the machine by forcing the rod to the right in Fig. 2 for releasing the endvof the rod 83 from the pintle 85.

'I'he lower edges of the plates or blades 80 are supported by a bar 91 which is secured at 98 to the bosses 86 and 9|.

` Since the gear |II (Fig. 2) 1s fast on the shaft Also mounted in the bosses 86 and 9| is a shaft |60. A plurality of discs lill are maintained in spaced relation on the shaft |66 by a plurality of sleeves I62received by saidshaft.

The discs lill are located in staggered relation with respect to the'discs 6I on the shaft 36. The discs 63 on the shaftll are located in staggered relation with the plates or blades 8U. Likewise the plates 'IG arelocated in staggered relation with respect to the discs 63 and the plates 66. This arrangement provides for 'Contact between these elements upon opposite sides of the soles as they are passing through the machine in order to prevent the paste which passes onto the blades 86 and thediscs IUI from being transmitted to the discs 6I and 63. v p

A chain |65 (Fig. 1) driven by a sprocket I9 on the shaft I9 is trained upon asprocket |66 on a shaft |61 and also on a sprocket I 66on the shaft lili) so that the shafts |60 and Ill'l are driven when the shaft I 5 is revolved. Totransfer motion to the various rotating members carried by the swinging `frame 35, a gear Ill) (Fig. 2), secured to the shaft 36 journaled in the frame, is

provided, said gear meshing with a gear Ill on the shaft |66 which is driven through the sprocket |08 and chain |55.

. A work supporting roll H2 carried by the shaft III'I is revolved by said shaftat substantially the same speed as the roll 52. y

A pair of standards I|5 rise from the` table IIJ and are provided with bearings `I l5 to receive a shaft Ill which carries a pulley ll uponv which a traveling belt ||9 is trained. A table |20 is 1 carried by the bearings ||6 and is adapted to receive the pasted soles before they are placed upon the traveling carrier I I9. i p

A pulley l2| is secured to the shaft` Ill and a belt |22 is trained on the pulley and is twisted and then tir'ained upon a pulley |23 secured to the shaft I6. `v

` The operation of my device is as follows: The shaft I9 is driven by the belt |22` (Fig. 1) trained on the drive pulleylZ l. Rotation `of the shaft I9 rotates the pasting cylinder I8 and the sprocket |921, and through the chain |65 applied to said sprocket rotation is imparted to the sprockets |68 and I 66 thereby causing rotation of the shafts |66 and |61 which carry the discs lill and roll II2.

it will be rotated by the chain'IIlS meshing with the sprocket I 68, and through the gear I|0 meshing with the gear I rotation is imparted to the sprocket l, and the shaft 36 (Fig. 4) which carries the discs 6I.

The chain 56 is driven by the sprocket 5l which in turn is driven by the shaft 36. The chain drives the sprockets 55 and 58. The discs 63 are revolved by the shaft 59 which in turn is driven by the sprocket 58. The roller 52 is revolved by means of the sprocket 55.

The set screws Ill are properly rotated for raising or lowering the free end of the frame 35 whereby the roller 52 will be properly positioned with respect to the roller l2 so that these revolving rollers will exert sufficient pressure on the soles when they are fed from the table lll to said rollers tocause the soles to be moved upon the top of the revolving paste cylinder i8 whence the curved edges 'I8 of the plate 'I6 will force the soles downwardly into contact with the revolving cylinder.

When the leading ends of the soles pass the revolving cylinder they will be supported by the spaced thin plates 86 while the revolving discs E3, will` engage the upper or clean surfaces in staggered relation with respect tothe horizontal edges of the p1ates80 and move the soles forwardly be.

tween-:the staggered discs 6| and I 6| which-.are being revolved whence the soles will be carried forwardly and finally are freed so that the operator may .place them upon the table |26. with the pasted face upwardly, whencethey may be moved manually upon the traveling carrier. I I 9.j

The scraper 26 will be properly adjusted with` respect to the revolving surface of the revolving cylinder` I8 bymeans of the'foperating rod 3|] so that excess paste will be forced away from the cylinder and be carried bythe curved surface of the plate I2; and beyond the wall I4 of the chamber I3.1By this construction the paste lwhich-has been removed from the cylinder will have tov flow around the side wall `I6 ,before it can enter the cham--A ber I3` so that` foreign matter may settle tothe bottom of theycontainer I2 and not f enter the chamber I 3 whereby thepaste will be maintained the staggered arrangement of the discs 63y with respect to the plates 86 and the staggered rela-` will prevent any excess of by the discs or plates. .i

Since the horizontaiedges 8| vof the plates 80 support the pasted face of thesoles when they leave the cylinder I8, said plates will collect paste and when desired these plates may `be removedbodily with the shaft 83 as has explained by forcing said shaft Fig. 2 againstthe tension of the spring I9 whereby the left hand end of the shaftwill be released'.l

from the pintle 85 and the plates 80 andthe shaft 83 may be removed as a unit.

The entire frame is removable as a `unit from the table by the release the bearings which support the shaft 36 through the set Vscrews 42 appreciated, however, that this is particularly true since the gear H5 may bep'laced in mesh with the gear Il I or removed therefrom when desired.

It will be seen by the present construction that only a very restricted contact is had between the moving parts for forcing the soles after they have been pasted from the machine and the staggered relation of the supporting and moving parts also aids in restricting the contact between the soles and the moving parts.

It will be noted that the machine will not only apply paste or adhesive efficiently to one face of pieces of material but will maintain the other face clean due to the fact that the feeding devices before and after the application of the adhesive are so constructed and operated that they will accomplish this result. The guiding and feeding elements are relatively thin so that only thin edges are presented to the surfaces of the materials. Furthermore, the increased surface speed of the revolving elements coming into contact with the materials after the application of the adhesive will pull the materials away from the of the sectionsv 38 `of and the yokes 43. It will be cylinder [8'v at a greater speed than the feeding in order to prevent back shoveling of the adhesive on the upper side of the materials. In other words the revolving feed rollers have a greater A speed of rotation than the pasting roller.
